Here is the schedule (also on the web site) of the formal/semi-formal/Pirate Night. I just reconfirmed this with
DCL, although the cast member reiterated again and again that it was subject to change.
Formal Night #1 - Thursday Dec. 13th
Semi-formal Night - Sunday, Dec. 16th
Pirates Night - Tuesday, Dec. 18th
Formal Night #2 - Thursday, Dec. 20th
So, dining rotation #1 would have a formal and semi-formal night at Animator's, a formal night at Parrot's and Pirate Night at Triton's. #2 has formal and semi-formal at Parrot's and 2nd formal at Triton's and Pirate Night at Animator's, rotation #3 would have formal and semi-formal at Triton's, 2nd formal at Animator's and Pirate Night at Parrot Cay. #3 seems to make the most sense but it doesn't matter that much.
And the CM did confirm that Monsers Inc. 3D will be shown on board.
